Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
Peel the sweet potato and white potato, then dice them into uniform 1/2-inch cubes for even cooking.
Place the diced potatoes on the baking sheet and toss with 0.5 tablespoon of olive oil, a pinch of sea salt, and half of the smoked paprika.
Roast the potatoes in the oven for 25 to 30 minutes, tossing halfway through, until they are tender and the edges are golden brown.
While the vegetables roast, combine the white rice and water in a small saucepan; bring to a boil, then reduce heat to low, cover, and simmer for 15 minutes.
Heat the remaining 0.5 tablespoon of olive oil in a large skillet over medium-high heat.
Add the ground beef to the skillet, breaking it apart with a wooden spoon or spatula as it browns.
Season the beef with the garlic powder, onion powder, remaining smoked paprika, sea salt, and black pepper.
Continue cooking the beef for 8 to 10 minutes until it is fully cooked through and slightly crispy at the edges.
Fluff the cooked rice with a fork and divide it into meal prep containers or bowls.
Top the rice with the roasted root vegetables and the seasoned ground beef to complete the power bowl.
